v0.0.2

🔄 Coming from aiortc? Install wrtc[aiortc], change from aiortc to from webrtc.aiortc, and your code runs on Chrome's engine. See the migration guide

⚡ Data channels 14x faster (57 to 812 Mbps), 47x over 10 connections, with 88% less CPU per MB

🪶 80% less memory per audio connection, 27% less per data channel connection, 1450 connections instead of 200

📊 Benchmarks against aiortc, Pion, libdatachannel and webrtc-rs: against aiortc, connections open 5–7x faster, a data channel moves 4.5–9x more data, and audio costs less CPU

🧪 Test coverage up to 93.4% for C++ and 99.0% for Python, with the bugs it found fixed

• Add an aiortc compatibility layer with a migration guide by @MarshalX in #245
• Add benchmarks against four WebRTC libraries, with results and charts by @MarshalX in #242
• Add a benchmarks page to the docs, linked from the README and the docs home by @MarshalX in #243
• Speed up data channels: callbacks run on the network thread, every queued UDP datagram is read on a read event by @MarshalX in #243
• Wake event loops through the mailbox's eventfd or pipe instead of the Dispatcher thread: a native event reaches Python in 45 instead of 84 µs (p50), the Dispatcher stays for Windows by @MarshalX in #243
• Wait with kqueue on macOS by @MarshalX in #243
• Skip empty gathering phases: setup without trickle takes 5 instead of 125 ms by @MarshalX in #243
• Drop the RTC event log, share one receive buffer per thread, stop listening on TCP and regathering by @MarshalX in #243
• Cut audio CPU per stream by 41–47% by @MarshalX in #243
• Play Janus streams without an audio output, as on servers by @MarshalX in #239
• Fix balanced and maintain-framerate never lowering the resolution by @MarshalX in #243
• Fix active TCP candidates rejected as a bad port by @MarshalX in #243
• Fix data channel messages arriving before the channel is announced, and a channel released before its last message is sent by @MarshalX in #243
• Fix sends from the datachannel handler lost before the channel opens by @MarshalX in #247
• Fix SFrame video recovery, and H.264 and AV1 with raw packetization by @MarshalX in #240
• Fix descriptions lost and iceGatheringState reading complete after close() by @MarshalX in #240
• Fix key frame requests of a removed script transform never settling by @MarshalX in #240
• Fix the received captureTime counted from the NTP epoch by @MarshalX in #240
• Fix rollback allowed in the pranswer states by @MarshalX in #240
• Fix a ValueError in set_parameters for a codec without a MIME type by @MarshalX in #240
• Fix maxMessageSize of a dropped or closed SCTP transport by @MarshalX in #240
• Fix remote video sent on to another connection, and a local description missing the candidates gathered after the remote one was read by @MarshalX in #245
• Fix a loop closed while its drain was scheduled never being released by @MarshalX in #241
• Fix a closing connection and its channels being active but unbound, and loop release by @MarshalX in #244
• Fix a watched loop's state never released after the loop closes by @MarshalX in #247
• Fix an abort when a task queue is deleted from its own task by @MarshalX in #247
• Fix flaky waits in tests on free-threaded builds and slow cores by @MarshalX in #241
• Run tests in parallel and fix the test races it exposes by @MarshalX in #247
